SPECIFICATION forming part of. Letters Patent No. 481,655, dated August30, 1892.

Application filed A ia 18, 1892.

To all whom it may concern:

Be it known that I, HENRY OLSEN, a citizen of the United States,residing at Winona, in the county of Winona and State of Minnesota, haveinvented certain new and useful Improvements in Fifth-Wheels; and I dodeclare the following to beafull, clear, and exact description of theinvention, such as will enable others skilled in the art to which itappertains to make and use the same.

This invention relates to an improvement in that class of fifth-wheelsin which the objectionable king-bolt is dispensed with; and, togetherwith a view of economy, it has for its object to give increasedsteadiness and strength and to simplify the construction, so as tomaterially lessen the liability of the parts getting out of order.

Other objects and advantages will appear zolfrom the followingdescription and claim when axle and bolster with spring in positiontheretaken in connection with the annexed drawlngs, in which I Figure 1is a front view of a portion of an on, showing the base plate or disk ofthe fifthwheel and the rabbeted ring in section. Fig. 2 is a perspectiveview of the parts comprising my improved fifth-wheel, the same beingillustrated as disconnected.

Referring by letter to said drawings, A indicates an axle, B a bolster,and O a spring, which may be of any ordinary or improved construction.

D indicates the top plate of my improved wheel. This plate, which issecured to the under side of the bolster B by means of bolts to and nutsI), is provided adjacent to its margin with bolt-holes c for a purposewhich will be presently described, and is furthermore provided in itscenter on its under side with a depending boss or annular lug cl, which,for the sake of strength and cheapness, is formed integral with saidplate D, which is preferably formed of steel, although it is obviousthat it might be made of other suitable material.

E indicates the base plate or disk, which is of much less diameter thanthe top plate D, and is provided on its upper side in its center with acircular socket or recess e, designed Serial No. 429,590- (No modeLl toreceive the boss or lug d of said upper or top plate. This base plate ordisk is provided with a rabbet f, which extends entirely around itslower marginal edge, as shown, and said base plate or disk is providedwith a plurality of apertures or holes g to receive bolts h, whichsecure said disk or plate firmly to the upper side of the axle A, andare secured in position by means of nuts 7; or other suitable fasteningdevices.

F indicates a ring. This ring is provided at suitable points around itsmargin with vertical holes is, corresponding with the holes 0 in the topplate or disk, and said ring is of a diameter corresponding with saidupper plate. The ring F is rabbeted, as shown at Z, so as to receive therabbeted edge of the base plate or disk E, and bolts or screws G arepassed through the aligned holes of the ring and top plate or disk forsecuring said parts together, and nuts m or other suitable means areemployed for fastening such parts.

I indicates an oil or lubricant cup, which may be of any suitableconstruction, and is arranged upon the top plate or disk D, so that itmay feed oil or other lubricant between the base and top plates orfrictional parts of the wheel.

A wheel as thus constructed will be found very cheap to manufacture. Itis simple in construction, durable in operation, and not liable to getout of order.

By reason of the peculiar construction of my improved fifth-wheel itwill be further perceived that no part of the bolster or the axle willbe subjected to frictional wear, and thereby their usefulness isprolonged.

Having described my invention, what I claim is- The combination, with awagon-bolsterand an axle, of the fifth-wheel consisting, essentially, ofthe following instrumentalities in combination, viz: the upper top plateor disk having a centrally-depending boss or lug on its under side andalso having bolt-holes through its body and at points around its marginfor the passage of bolts which connect it to the axle, the base plate ordisk having a central recess or socket on its upper side to receive saiddepending boss or lug of the top plate or disk and rabbeted on its undermarginal edge and also having bolt-holes in its body for the passage ofbolts, which eonnect it to the axle, a ring rabbeted to receive therabbeted edge of the lower plate or disk and having holes to registerwith the marginal holes in the upper plate or disk, and bolts or 'thelike for securing the ring to said upper plate, and consequently thelower orbase plate thereto, substantially as specified. 1o Intestimonywhereof I affix my signature lIl presence of two witnesses.
